For Y'all Data - Fossil Of Oldest Long-Necked Dinosaur Constitute Inwards Brazil

H5N1 grouping of paleontologists discovered inwards southern Brazil what has been described every bit the world's oldest long-necked dinosaur, academy researchers said Wednesday. Their findings are based on analysis of iii well-preserved dinosaur skeletons.

The description of the novel dinosaur species made past times researchers at the University of Sao Paulo (USP) together with the Federal University of Santa Maria (UFSM) was published inwards the latest edition of the scientific magazine Biology Letters.

The novel species, named "Macrocollum itaquii," purpose of a grouping of dinosaurs known every bit sauropodomorphs - was identified after iii consummate dinosaur skeletons were removed inwards 2013 from Triassic rocks inwards Agudo, a municipality inwards the interior of the southern Brazilian acre of Rio Grande create Sul, which borders Argentine Republic together with Uruguay.

The master copy characteristic of the newly identified species is its long neck, which stretched for 3.5 metres (almost 12 feet).

That characteristic places the "Macrocollum itaquii" inwards the same grouping of sauropodomorph dinosaurs that too includes Brachiosaurus together with Apatosaurus.
